Application filed. June 27,

To all whom it may couccm:

li e it known that I, rlnrnonsn E. limos, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and hltate of Ohio, hove inrented a new and useful Attachment for Manifoiding Type writers. cit which. the following is a specification.

This invention is a device designed for attachment to Inanifoldino; typewriters and the like and has for an object automatically to unwind the rolls oi paper usually em ployed to furnish the necessary supply of paper to such typewriters. so that suiiicient slaclr maintained till times to enable the several sheets of paper to be fed easily upon rotation at the platen, as well as to i ierniit of free movement of the typewriter carriage during the writing; operation.

This and other objects are attained. in the device now to be described and which has been illustrated in the accompanying drew ing. in which:

1 is perspective view of a manifolding typewriter having an attachment embodying my invention attached thereto, a roll paper supply raclr being shown in connection therewith.

Fig 2 is a perspective view upon on on lsrged scale, of the device embodying my invention.

3 is an enlarged sectional view taken on the line 3-3 ot Fig. 5%.

Fig. 4 is an enlarged fragment-cl perspeo tive view of a portion or the typewriter trains, showing the outside thereof and the means I employ to secure a portion of my improved device to the typewriter.

Fig. 5 is a view of the same "features shown in Fig. 4:. but disclosing the reverse or inside of the frame and securing means.

In manifolding typewriters an extension 6 of the usual typewriter frame 7 carries a transversely extending: track 8 upon which a. rearward extension 9 of the usual carriage of the typewriter travels. At the rear of extension 9 a transversely extending rod 11!. is provided, over which the several superimposed sheets oi. paper 12 pass from series of supply rolls 13. which are conveniently located as shown, to the platen 14 of the carriage. Suspended from bar 11 are the two side members 15 and 16 of a swinging freme. These members: are spaced. apart by vm GOMPAJIY, 0ft? GINGINIFJATI.

rods 1'? and 18 and beneath rod 18 a. roller 19 is mounted between members 15 and 16. The hooked ends 20 and 21 are held against removal from. the rod 11 by screws 22 pass ing through the members beneath the rod. Thus the frame is free to be swung torwardly and baclrwardly. Attached to -t'raine 6 I have provided a looped track 523 which extends rearwardly and is secured to the typewriter frame. at its ends 24- end 25 by clamps 2G and Q7 which are attached to the frame by thumb screws 28, the ends being secured in the clamps by set screws .29. A frame swinging link or push rod is connected pivotally to rod 1'? by a yoke 31 to which it is riveted as shown in Figs. 2 and 3 and is prevented from sliding along the rod by a screw 32 entering a slot 33 therein. This link is attached detachabl v to the track 28 by means of a grooved roller 34C and a. pin 85. the roller beingmounted on the end of liulr 30. the pin being mounted on a spring 36 extending from. link 30. The pin and roller are arranged to engage opposite sides of the track shown in 2 and attachment and detachment is eiiiected by lifting upon the spring to bring the pin away from the track 23.

in the operation of the device the sheets 01E paper from the rolls located in convenient position. preferably to the rear of and beneath the typewriter. are drawn over the roller 19 to the rear of the swinging frame and laid in superimposed. relation to each other upon the carriage and its extension. and brought over the platen in the usual manner. The connection of link 30 with track 23 having been accomplished, the device will now function in the following manner.

Each time the carriage traverses its track it carries with it the swinging frame which in turn carries the link 30 held at right angles thereto. This causes roller 34. by reason of its connection with track to follow the track and move the frame forwardly and boclrwardly. At each end of the carriage movement the frame moves forwardly and between these limits of carriage movement the roller forces the frame bachwardly as it travels over the peak 37 of traclr The efi'ect of this movement of the swinging frame is to pull upon the paper coming from the rolls and to cause them.

thus to unwind sufficiently to produce enough slack so that the line spacing may be accomplished readily without eliort or slippage each time the platen is rotated at either end of travel. of the carriage.

Having thus described my invention what I claim is:

1. An attachment for manifolding typewriters comprising a swinging frame pivotally attached to the rear of the carriage and located beneath the paper passing over the carriage and in engagement therewith, a track rigidly attached to the typewriter frame adjacent to the swinging frame, and means operatively connecting the track and swinging frame, adapted when the carriage is reciprocated to move the swinging frame, whereby the paper in engagement therewith will be caused to become slack upon completion of the swinging movement 01 the frame.

2. An attachment for manifolding typewriters, comprising in combination with a mani'folding typewriter and a roll paper supply rack, a swinging frame pivotally attached to the rear of the carriage and located beneath the paper passing over the carriage from the rack and in engagement therewith, a track rigidly attached to the typewriter frame adjacent to the swinging frame, and means operatively connecting the track and swinging frame, adapted when the carriage is reciprocated to move the swinging frame, whereby the paper in engagement therewith will be caused to be unrolled from the rack and to become slack upon completion or" the swin in movement of the frame.

3. An attachment for manitt'olding typewriters comprising a track adapted to he attached ri idly to a typewriter frame, a swinging rame adapted to be attached pit-- otally to a typewriter carriage, and a link connected with the frame and operating over the trac n adapted to move the frame when the earlis Lined, said tr cl: having a shape adapted to produce greatesttrame movement between the limits of movement 01. the carriage.

4-. An attachment for manifolding type writers comprising in comhination with a typewriter and a paper supply rack therefor, a swinging :trame pivotally attached to a paper moving element 0'? the typewriter and depending therefrom, roller at the lower end of the swinging frame adapted to engage the paper passing from the rack of the typewriter, a substantially l-shaped track rigidly attached to the typewriter :trame adjacent to the swinging frame, and a roller carryim push rod ri idly attached to the swinging frame and extending therefrom into contact with the track, adapted to swing the frame when transverse movement of the carriage causes movement of the push rod roller over the track, wherel'iy the frame will be swung during passage of the roller over the peak of the track between the limits of movement of the carriage.
